If a dropdown menu is locked upon picking a specific illustration, it is because it has to be N/A for that choice! Keep in mind when switching between High School Life, University Life, and Love Life, the properties will temporarily "stick"--simply pick a different illustration and go back to the one you were on and it'll properly adjust.
Last Updated: June 14th, 2021 for the Music Day Event - sorry this is late, crazy week and I got the date wrong
